Painful to complete on the Hunter despite running Shinobi’s with the double skip grenades but eventually got it. Painful to complete on the Warlock despite running Sunbracers and top tree Dawn Blade with Celestial fire and solar grenades. 4 matches on the Titan and not as painful. 29% completed running Skulfort, top tree Striker, with double pulse grenades. Some guardians the shoulder charge is no longer a 1HK but for many it still does the trick. Like many aspects of this game, you gotta grind it out wth what works for your play-style.
